The Corruption Eradication Commission (KPK) said that it had already investigated allegations that two police officers formerly assigned to the antigraft body tampered with evidence.

“The internal affairs team had conducted an investigation into the parties that were suspected of knowing or conducting activities that violate KPK employee disciplinary [rules],” KPK spokesman Febri Diansyah said on Monday.

“During the investigation process, the KPK received a request to return the officers to the National Police because they were needed there, so the two KPK employees were returned to their original institution.”

The accusations came to light on Monday through a report published by IndonesiaLeaks, an independent whistleblower platform co-founded by Indonesian media outlets and civil society organizations.

The report found that CCTV footage from April 2017 allegedly show Adj. Sr. Comr. Roland Ronaldy and Comr. Harun, who were assigned to the KPK as investigators at the time, tearing and altering pages from a financial records book.

The book was among the evidence that was confiscated in a bribery case involving meat-importing businessman Basuki Hariman and former Constitutional Court justice Patrialis Akbar – both were sentenced to jail in September 2017.

Febri said the KPK's internal investigation stopped when Roland and Harun returned to the police in late 2017.

Despite the allegations, Roland has since been promoted to Cirebon Police precinct chief in West Java, while Harun is the head of a subdivision in the Jakarta Police's Special Crimes Directorate. (kuk/kmt/ipa)
